Subject: [PATCH V2 12/14] ARM: dts: sb-som: introduce SB-SOM baseboard
Date: Tue,  1 Dec 2015 15:55:07 +0200	[thread overview]
Message-ID: <1448978109-5614-13-git-send-email-nikita@compulab.co.il> (raw)
In-Reply-To: <1448978109-5614-1-git-send-email-nikita-UTxiZqZC01RS1MOuV/RT9w@public.gmane.org>

CompuLab SB-SOM baseboard is a carrier board for multiple arm-based SoMs.
It currently supports (with minor adjustments to assembly) CM-T43, CM-T54,
and CM-QS600 modules. It is a building block in the SBC-T43 single board
computer, which consists of cm-t43 on top of sb-som-t43.
